REGULATOR.

SPECFICATION forming part of Letters Patent No. 335,734, dated February 9, 1886.

Application filed December 21, 1885. Serial No. 186,258. (No model.)

To all whom, it may concern.-

Beit known that I, JOHN AcToN, of the city, county, and State of New York, have invented a new and useful Improvement in Pressure-Regulators, of which the following is a specification.

Pressnreregulators are generally employed in connection with heating buildings by steam, and the same are placed on the line of steampipes between the source of supply and the radiators, and difficulty has been experienced in keeping the regulators steam-tight and in proper working order.

My invention relates to a regulator having diaphragms which are sealed by water or otherliquid, and thus protected from direct action of the steam, and in which the opening and closing of the piston-valves are regulated by the diaphragm and Weighted levers.

In the drawing I have represented my improved pressure-regulator by a vertical section in which the steam inlet7 and exit7 are lettered and accompanied by arrows.

The case of the'pressure-regulator is made of metal, with the various parts bolted or otherwise connected together.

a a are the piston-valves upon the stem b, and said valves are made with guides a2 a3, that project as segments of rims that prevent the valves moving laterally. The stem is made in three parts, I) b b2, which are preferably screwed together, andthe diaphragms c d are held between the part-s b and b and b and b2, and the outer edges of said diaphragms are secured between the sections A Al and AZand A3, respectively, of the case of the regulator.

The weight and lever e are pivoted at e to the regulator-casing, and connected at e2 in a slot in the stem b2; and the action of said weight and lever is to raise the stems b b b2 and open the valves u. a and admit steam to pass through the regulator to the radiators. The spring t' and wheel i serve to adjust the parts so that they act under the desired press ure.

Vit-hin the case A, above the diaphragm c, and around the stem b, there is water or other' liquid, and the chamber f above the diaphragm dis also filled with water, and there is a pipe, h, connecting the chamber f with the steam-chamber A at the exit side of the regulator, and said pipe h also becomes filled with water or other liquid, and there is a valve or cock,h, that can be closed to shut off the pressure when desired, The chamber beneath the diaphragm d is open to atmospheric pressure.

The operation is as follows: Supposing the valves a a to be opened by the action of the weight and lever e, the steam passes freely to the radiators. If the pressure becomes excessive, the same, acting through the medium of the water in the chamber f, forces down the diaphragm d and draws down the diaphragm c, and through the stem pulls down the valves a a and shuts off the supply of steam. As soon as the steam-pressure in chamber A falls by the cooling and condensing of the steam the pressure upon the water and diaphragm dis lessened, thus allowing the weight and ,lever e to again act and raise the valves a a and admitting steam to pass to the radiators.

If the diaphragm d should break, the valve h can be closed and the esca-pe of steam be prevented; and if the diaphragm c should break the diaphragm d willprevent the escape of water and steam; and if both diaphragrns should break, or it should become necessary to shut off the vsupply of steam, the chain k can be employed t-o hook up the lever e and keep the valves a a closed.

I claim as my invention.

l. The combination,in a pressure regulator, with the valves a a and weight and lever e, of the stem b b b2, the liquid-sealed diaphragms e d, and a connection from the chamberf to the steam-chamber A, substantially as set forth.

2. Ina pressure-regulator, the valves a ct and weight and lever e, in combination with the stem b b b2, theliquid-sealed diaphragms, c d, apipe, h, and valve h,.the parts being so constructed that there is a liquid-chamber around the stemb above the diaphragm c, and a liquid-chamber, f, around the stem b, and above the diaphragm d, and communicating by the pipe 7L with the chamber A, for the purposes and substantiall y as set forth.

3. In a pressure-regulator, the valves a a and stems b b b'in combination with aweight and lever, e, and hook and chain L, whereby the lever can be hooked up and the valves a a closed, substantially as set forth.
